CHARLES WEBER, OF PITTSBURG, PENNSYLVANIA.

ROLL FOR BENDING STRUCTURAL IRON.

SPECIFICATION forming part of Letters Patent No. 600,700, dated March 15, 1898.

Application filed September 28, 1897. Serial No. 653,365. (No model.)

To aZZ whom it may concern:

Be itknownthat I, CHARLES WEBER, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Rolls for Bending Structural Iron, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in rolls for bending structural iron, and has for-its object to provide novel means whereby the collar of the roll may be readily adjusted to conform to the different thicknesses of metal without necessitating the changing of the rolls in the housing.

The invention further aims to provide means for easily and quickly changing the position of the collar upon the rolls and for securing the same in the desired position.

This invention should be considered in connection with one filed by me on September 9, 1897, Serial No. 651,068, and is an improvement thereon, and in order to describe the invention in detail reference will be had to the accompanying drawings,formin g a part of this specification, and wherein like letters of reference indicate similar parts throughout the several views, in which- Figure I is a front view of a set of housings with the rolls therein, the upper roll being constructed in accordance with my invention and the lower roll being of the ordinary form. Fig. 2 is a longitudinal sectional view of a portion of my improved roll. Fig, 3 is an end View of the same. Fig. 4 is a sectional view of the adjustable collar. Fig. 5 is a cross-sectional view of the improved roll, taken through the collar. tive view of the key for wedging or locking the collar in the desired position.

Referring now to the drawings by referenceletters, a represents the housings, which are or may be of the ordinary construction and provided with the usual means for vertical adjustment of the rolls. My improved roll is or may be journaled in these housings in the usual manner, and for about one-half of its length the same is reduced in form, thus producing a shaft c having exterior screwthreads throughout its entire length and also Fig. 6 is a perspec-` provided throughout its length with a series of keyways c', which are adapted to receive the fastening-key CZ for locking the collar in its desired position upon the shaft or screwthreaded portion of the roll. The remaining portion e of theroll may be of the ordinary form of construction, and mounted upon this screw-threaded portion of the roll is an adjustable collar f,which is of the same diameter as the portion e of the roll, said collar being provided with a keyway g to receive the key d for fastening the same in position, and in order to complete the roll between the collar f and its adjacent housing I provide a large sleeve-nut h, the head or large portion k of the same being of the same diameter as the adjustable collar f and the portion e of the roll, thus completing the roll. The said sleeve-nut is also held in position by the fastening-key d, and the reduced portion of this sleeve-nut forms the bearing within the housing.

In Fig. l of the drawings the rolls are shown adjusted so as to form certain sizes of angleiron, and it will valso be observed that the same style of roll may be employed for I- beams, T-iron, and various other forms of material of this nature used for structural purposes. After the collar f has been adjusted to the desired position the sleeve-nut may then be adjusted firmly against the same, if desired, so as to give a solid roll between the adjustable collar and its adjacent housing, and by the provision of `a series of keyways around the periphery of the screw-threaded portion of the roll the collar may be readily adjusted so as to accommodate any thickness of iron, the fastening-key d, of course, being removed while the collar is being turned and inserted in the respective keyway corresponding with thel keyway in the collar when the same has been placed in the desired position. In Fig. 1 I have shown the 4lower roll e as of the ordinary construction, though, of course, for certain forms of iron my improved roll may also be employed for the lower as well as for the upper roll.

It will also be noted that various changes may be made in the details of construction IOO my invention.

Having fully described my inventioru-What I claim as new, and desire to secure by Letters Patent, is-

l. In rolls for bending structural iron'and the like, consisting of a roll having a reduced screw-threaded portion, a movable and adj ustable collar mounted thereon and provided with a keyway, a series of longitudinal key- Ways formed in said reduced portion and a key adapted to engage the roll and collar so as to lock the collar at a desired point on the roll, substantially as shown and described.

2. A roll having a reduced screw-threaded portion, an adjustable and removable collar mounted thereon, said collar being of the same diameter as the roll, and means for locking said collar in any desired position, substantially as shown and described.

3. The removable and adjustable collar mounted upon a reduced screw-threaded portion of the roll, said collar being of the same diameter as the roll, keyways formed in said reduced portion, a keyway formed in the collar and a key for looking the collar in any desired position, substantially as shown and described.

4f. The adjustable collar mounted on the screw-threaded portion of the roll and being of the same diameter and a key adapted to 4engage the roll and adjustable collar so as to lock the collar at any desired point, substantially as shown and described.

In testimony whereof I afiix my signature in presence of two Witnesses.

CHARLES VEBER.
